Matric part 1 Chemistry, Gram Atomic Mass - Che Ch 1 Fundamentals of Chemistry - 9th Class Chemistry

[@sadiashaikh3852]

He taught very well but At 3:05 sec he said that number of protons are equivalent to atomic mass well that's wrong because number of protons are equivalent to atomic number and number of protons +neutrons are equivalent to atomic mass... and also that atomic no.of sodium=11 and atomic mass=22.99~23.

Sadia Shaikh u right

[@YousafKhan-zj4ct]

The topic is taught by the teacher but there are two points that needs clarification.. 1. The no. of protons in nucleus is not atomic mass but atomic number. 2. the gram atom and gram molecule is not equal to 1gram but these are the mass equal to the amu or atomic mass or molecular mass expressed in grams which is further equal to 1 mole of a substance. Note. This is only for correction and my view as a teacher. Thanks and regard

Hello sir.. i have one doubt. Gram atomic mass is mass of 1g of atoms but when we have taken 1 gram atoms how its mass can be more than 1. like for carbon how it can be 12g

[@hanifraja176]

when you express the atomic mass of the individual atom in grams it is called Gram atomic mass,,, and carbon has 12 atomic mass so obviously will be 12 grams... oxygen has 16 atomic mass so will be 16 grams...

[@wahabmughal1790]

[@ahlaywatan1]

when atomic mass is the gram atomic mass then why gram atomic mass of hydrogen is1.008g because there atomic mass is1 please explain

[@nimirajpoot6238]

@@ahlaywatan1 atomic mass of hydrogen is also 1.008 that's why gram atomic mass is 1.008g

Atomic mass of sodium is 23 u. As it has 11 protons and 12 neutrons. 11+ 12 = 23 u.

[@waliharimzi7529]

So what hes trying to say is that 1 amu=1 gram?? Amu is used to represent mass number right? So does that mean that 1 amu equals 1 gram? If anyone understands this plz answer yes or no?

The gram atomic mass of a substanc is represent 1 mole of atom of that substance... Matlab ki 1 mole me kitna atom hota hai un savi ka mass k sum ko atom ka gram atomic mass kehte hai I hope you'll understand

[@gulzarshaikh5525]

Mass of one mole of atoms of an element is in gram is called gram atomic mass. Mass of one mole of molecules in gram is called gram molecular mass and one mole is equal to 6.022*10to the power 23
